12(S)-HETE

12(S)-HETE is an arachidonic acid metabolite synthesized in the 12-lipoxygenase pathway in platelets and macrophages. Studies suggest that 12(S)-HETE is a potent stimulator of smooth muscle cell and leukocyte migration. In addition, this metabolite can induce reversible endothelial cell retraction allowing tumor cell access to the subendothelial matrix, which is not activated by 12(R)-HETE. Furthermore, studies show that a potential use of this molecule could be in preferentially attracting eosinophils to tissue reactions associated with platelet activation.
